IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 131,165, datedSeptember 10, 1872.

Know all men by these presents:

That 'I, GEORGE W. HARDY, of the city of Grand Rapids, county of Kentand State of Michigan, have invented certain new and useful Improvementsin Spring BedBottoms, of which the following is a specification:

My invention relates to a metallic springbrace used in combination withthe upper and lower frames of an ordinary coiled-spring bedbottom, forthe purpose of holding the upper and lower frames firmly in their properrelative position, and for the further purpose of giving greaterelasticity to the bed-bottom.

In the accompanying drawing, Figure 1 shows a perspective view of abed-bottom to which my invention is applied. Fig. 2 is a side view ofthe same; and Fig. 3, one of the sprin g-braces.

In Fig. 1, B B are side pieces of the lower part of the bed-bottom A A,the upper frame of the bed-bottom. S S are metallic springs constructedout of metal formed into thin strips and riveted together at rightangles, in the form of an ordinary carpenters square, substantially asshown in Fig. 3. In a bed-bottom to which my invention is applied thelower frame is made smaller than the upper frame of the bottom, and thespring-brace is attached to the lower surface of the end frame of theupper part of the bed-bottom and to the upper surface of the side pieceof the lower frame of the bed-bottom, the attachment being effected byscrews, nails, rivets, or in any other suitable manner. is shown inFigs. 1 and. 2 of the drawing. I use four of these spring-braces in eachbedbottom, one at each corner, the spring-braces being placed bracing,as shown in the drawing. As the upper and lower frames of the bed-bottomare pressed together the elbow or angle of the brace is forcedoutwardly, giving a twisting pressure to the metallic pieces composingthe brace, thereby increasing its elasticity. A piece of ordinarywebbing may be used to prevent the upper and lower frames of thebed-bottom from. being forced too far apart by the springs orspring-brace, as shown in Figs. 1 and 2, by E. g

I make no claim upon the frame-work or webbing; but

What I do claim to have invented, and desire to secure by LettersPatent, is- The right-angled metallic spring-brace S S, in combinationwith the upper frame A and lower frame B B, when constructed andarranged substantially as and for the pur: poses herein set forth.
